algebra 2

A. I need to write an equation to the linear equation..(-2,-2), (3,3).
B. I need to graph the function of y=|x| on a coordinate plane.
C. I need to give one similarity and one differnce for the equations and graphs in parts A and B.

I really need your help on this i don't understand at all...so if you can show me step by step then i can do my other math homework...i appreciate it. thanks!!

  1. A. Find the slope (rise/run). Plug x and y into your equation with the slope to find the y-intercept and then you'll have your y=mx+b equation.

    B. Should look like a "V" shape open upward starting at the vertex at (0,0). Basically "x" can be any number and "y" must be greater or equal to 0.

    C. Base on your findings on A & B, you should be able to answer this question. Compare the slopes or y-intercept and you can see that on part B, there's a restricted value for the y values and part B has no restriction...etc.

  2. I would add to B that the lines depart the origin at 45 degrees from the x (and y) axis.

    Both involve straight line graphs at 45 degrees to the axes
    the first one has a y range from - infinity to + infinity.
    The second one has a y range from 0 to + infinity as Jake said.
